This one is knit with Austerman “Peru” Alpaca yarn (now discontinued, I’m afraid). It’s a lovely soft “sport” weight Alpaca.
This shows that although a fingering or sock yarn is recommended a sport weight yarn will work just as well.
I used the same needle size (2.5 mm) and the same # of stitches. This one is for Aidan. Hope you like it kiddo?
Earl (DH) is jealous. He thought it was for him so I’ll get to work on another one. Since I can’t make the same hat twice I’ll make his out of black (it must be black) sock yarn. I’ll keep you posted but I can’t start it until I finish

Hi Rose, I always use the same number of stitches as the ribbing is very stretchy. The only size difference is the length. you can make that anything you like. Here are the suggested finished measurements.
Finished Measurements: 15 inches around and 8.5 (9, 9.5) inches in length.
If you do decide you need more width be sure to add enough stitches to make the decrease row work out correctly. This would require a multiple of 26 sts. Have fun with it 🙂
